-- The following record fields are available, with the corresponding lenses provided

--
-- 'blobValue', 'field_blobValue' - A value of the BLOB data type.--
-- -- /Note:/ This 'Lens' automatically encodes and decodes Base64 data.
-- -- The underlying isomorphism will encode to Base64 representation during
-- -- serialisation, and decode from Base64 representation during deserialisation.
-- -- This 'Lens' accepts and returns only raw unencoded data.
--
-- 'booleanValue', 'field_booleanValue' - A value of the Boolean data type.
--
-- 'doubleValue', 'field_doubleValue' - A value of the double data type.
--
-- 'isNull', 'field_isNull' - A value that indicates whether the data is NULL.
--
-- 'longValue', 'field_longValue' - A value of the long data type.
--
-- 'stringValue', 'field_stringValue' - A value of the string data type.
